I just installed the 5.0 Beta3 on a CentOS5 box and everything seems to be working, but I am not able to configure the GAL or Authentication without getting a JavaScript error.

This is the error that appears when I try to click the FINISH button.

name: TypeError
message: 'this._app' is null or not an object
